Tracking Your Children with GPS
Using the Global Positioning System, the service allows parents to track up to four cell phones over the Internet or on their own wireless device. Parents can periodically ask the service to find the child's phone, displaying the location on a road map.
Parents can also set alerts, automatically warning the parent if the child isn't at a certain place, such as school or soccer practice, at a specific time. Fox News-Full Story

Not intended for jealous, insecure, over-dominating adults i.e. mates and spouses. (smiling) GPS tracking systems!!! (lol)
